Cages of Drawn Shells, fully described and represented in the following specification and the accompanying drawings, forming a part of the same. p

This invention relates to a self-contained set of rolls for roller-bearing, the set comprising a cage to guide therolls in their working position in the casing of the bearing, and formed of two cyilindrical shells ,tted to the inner and outer sides of the rolls, and two annular heads which are embraced by flanges bent upon the ends of the shells.

The cage may be employed with solid rolls, or with tubular rolls formed of a spirally wound strand.

The construction will be understood by reference to the annexed drawing, in which-- Figure 1- is a longitudinal section of a hearing on a vertical line through the center of Fig. 2, with the shaft embraced by the rolls. Fig. 2 is an end-view of the rollset with a shaft showh inside the rolls; Fig. 3 is a section of the cage at the ends of the rolls on line 3-= 3 in Fig. 4; Fig. 4L is a side elevation of the outer shell of the-cage; Fig. 5 is a side elevation of one end of the inner shell of the cage; and Fig. 6 is an end view of one of the heads adapted to fit within the ends of the cage.

The bearing of Fig. 1 is shown with a cylindrical casing a with annular plates 6 at its opposite ends through which the shaft or axle a extends. The rolls 0 are proportioned to contact with the shaft on the inner side of the casing.

The outer shell of the cage is made from a section of cylindrical tubing or drawn sheet-metal, and is furnished at its ends with two collars (Z and e, and longitudinal slots f extending between the collars and having longitudinal bars 9 at the edges of the slots. The metal punched from the slots is bent inwardly from the edges of the bars 9 forming wings kwhich are shown radial to the surface of the rolls, and at a suitable distance apart to fit opposite sides of the rolls, as shown in Fig. 3.

The inner shellof the cage, as shown in Figs. 3 and 5, has longitudinal slots f punched through it between end-collars cl, such slots forming bars 9 at suitable distances apart to touch the inner sides of the rolls at opposite points, thus holding them in the. cage while permitting their free movement.

The inner sides of the rolls project through the slots f into contact with the 'axle or shaft to which the bearing is applied, as is indicated by the dotted circle marked a in Fig. 3. To combine these two shells into a workin cage, annular heads j are formed with tli eir outer edges to fit against the interior of the collars (l and e of the outer shell, and upon theirv inner edges to fit the exterior of'the collars cl upon the inner shell.

Flanges e are shown bent inwardly from the outer ends of the collars d and e to fit upon the outer sides of the heads j, and where it is desiredto make the flanges flush with such outer sides, the heads may be rabbeted, as shown at 70 in Figs. 1 and 6. Flanges Z are similarly formed upon the outer edge of the inner shell, and corresponding rabbets 70 upon the heads j. The flanges e and Z are formed upon the two shells after the rolls are inserted therein and the heads fitted between the inner and outer shells. The flanges e and Z are then readily spun upon the shells by suitable means, which thus locks the shell and heads together and forms a rigid cage-structure; the heads during such spinning operation being crowded against; the ends of the wings 72. which holds the heads parallel and at right angles to the axis of the shell. The entire structure is made very cheaply and forms av IIlOStfilClBIlt cage for a self-contained roll-set in a roller-hearing.

It will be observed that the wings it upon the outer shell and the bars 9 upon the inner shell hold the rolls movably without permittingthern to fall out of the cage,gand the cage thus requires no projections toengage the ends or bores of the rolls, and is thus adapted for use with solid rolls, as shown in the drawing.

Having thus set forth the nature of the invention what is claimed herein is:

1. A- cage for the rolls of a roller-bearing, consisting of inner, and outer shells each having slots for the passage of the rolls and the shells connected by annular heads at their opposite ends.

- 2. A cage for the rolls of a roller-bearing, consisting of inner and outer shells each having collars at the ends and slots for the passage of the rolls and the shells connected by annular heads fitted to the collars.

3. A cage for the rolls of a roller-bearing, consisting of inner and outer shells each having collars .at the ends and slots for the passage of the, rolls with wings bent into contact with the rolls from the slots of the consisting of inner and outer shells each having collars at'the ends and slots for the passage of'the rolls withwings bent into contact with the rolls from the slots of the outer shell,'annular heads fitted between the shells and having their inner and outer heads rabbeted, and flanges bent from the ends of the shells into the said rabbets to hold the heads in place.

6. A cage for the rolls-ofa roller-bearing, consisting of inner and outer shells each having collars at the ends and slots for the passage of the rolls with Wings bent inwardly from the outer shell to contact with the outer sides of the rolls, annular heads fitted between the shells in contact with the ends ,of the said wings, and flanges bent from the ends of the shells over the outer sides of the heads to hold them firmly against such wings.

In testimony whereof I have hereunto set my'hand.
